WINDOW-SCREEN.

SPEGIFIGATTON forming part of Letters Patent No. 254,561, dated March 7, 1882.

Application filed April 29. 1881. (No model.)

To all whom it may concern:

Be it known that I, SILAs MEAD, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Window-Screens, of which the following is a specification.

My invention relates to sliding windowscreens that may easily be put in or taken out ofa window; and it consistsin a grooved frame and springs carrying blocks made to work against grooved detachable strips, said strips having a ,stop covering the edge of the screen.

Figure l is a front elevation.- Fig. 2 is a cross-section on a line :20 m, Fig. 1. Fig. 3 is a detailed view.

My screen A is secured in a frame, B, having the side pieces, 0, grooved to fitand slide in grooved strips D D, attached to thewiudow frame or stop EA These strips are constructed with the rib H and the front flange-stop, K, madeto cover the edge of the screen-frame in its contact with the strip and make a closed When the screen is to be putin position the wood sections are placed against the rib H and the frame is pressed in the direction of this rib, the springs yielding to let the rib enter the groove 1 in the side of the frame, so that the opposite side may pass into sliding connection with the strip D. The springs also serve to hold the screen at any point of elevation.

To remove the screen it is only necessary to press it toward the rib El, when it may be readily taken out.

I am aware of the patent of O. A. Werden, No. 157,560, December 8,1874, and of the patent of E. T. Burrows, No. 210,495, December 8, 1878; but I have'not and do not claim the invention of either.

The window-screen having in the edges of the frame the groovesand in one of said grooves the contact-sections G, actuated by the spiral springs F, in combination with the detachable strips D D, having the ribs H and flange-stops K, substantially as and for the purpose specified.

SILAS MEAD.
